G063344525 22.4 mm Dia. UVFS Mounted Double-Concave Lens; EFL=-20mm 725-1050nm
This is a G063344525 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is mounted on UVFS (Ultra-Violet Fused Silica) material, identified as UVFS MAL-1965, which is known for its excellent transmittance in the ultraviolet, visible, and near-infrared spectral regions.
The lens has an effective focal length (EFL) of -20mm, making it a concave lens that diverges light. This type of lens is often used in applications where beam expansion or divergence is required. The lens's concave-concave base shape is circular, which is a common shape for optical lenses due to its symmetry and ease of manufacturing.
The lens's front and back surfaces are coated with Qio Bbar Arb2nirnbk7, a broadband anti-reflection coating that reduces surface reflections and increases transmission. This coating is designed to operate in the 725-1050nm wavelength range, making it suitable for near-infrared applications.
The lens's geometry includes inner and outer radii of 0, indicating that it is a simple spherical lens. The radii of curvature for the first and second surfaces are -20.535mm and 20.535mm, respectively.
This lens is available from Qioptiq Photonics and is currently in stock. For more information, please refer to the provided weblink.
